Anchor Strap/Chain
– Tree saver anchor straps are made of high quality nylon with
high tensile strengths from 5,000lbs to 10,000lbs.
Heavy Blanket
– place on the cable to absorb energy should the wire rope break.
RIGGING TECHNIQUES
Self-Recovery
Locate a suitable anchor such as a strong tree trunk or boulder.
Always use a sling as an anchor point.
CAUTION
Do not attach
the clevis hook back onto the cable as this could cause damage to
the cable.As shown in Fig 3.1
CAUTION
Do not winch from an acute angle as the wire rope
will pile up on one side of the drum causing damage to wire rope
and the winch. Fig 3.2
Short pulls from an angle can be used to straighten the vehicle.
Long pulls should be done with the wire rope at a 90° angle to the
winch/vehicle.
When pulling a heavy load, place a blanket or jacket over the wire
rope five or six feet from the hook. In the event of a broken cable it
will dampen the snap back. For additional protection open the
hood of the vehicle as shown in Fig 3.3
For pulls over 70% rated line pull, we recommend the use of the
snatch block/pulley block to double line the wire rope. Fig 3.4
This reduces the load on the winch and the strain on the rope by up
to 50% depending on the included angle.
WARNING -
Never use your winch for overhead hoisting or for
lifting people or moving people.
